This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X960, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.

The AirTAC Airtac SI200 Standard Cylinder SI200X960 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 960mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X960, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI200X960 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 960mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the direct replacement SAI200X960. The SAI matches the ISO 15552 mounting interface, bore, stroke, force, and port exactly. Because this SKU lacks the -S magnet, it cannot accept a position switch. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure, and adds SAIL and BSAI lock variants absent from the SI line. For high heat, Viton H seals raise the limit to 150 C.
Note that a plain cylinder drifts without live air; the cushion only decelerates. Use an external rod lock or pilot check valve for load holding.

| Max (@1.0 MPa) | 3204 kgf | |
The SAI200X960 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Provides the high 15708 N push force at 0.5 MPa needed to actuate large heavy-duty stamping presses.
Uses the 960mm stroke to raise and lower industrial palletizing lift gates through a long vertical travel path.
Secures heavy injection molds with a theoretical max output of 3204 kgf at 1.0 MPa operating pressure.
To replace the SI200X960, order the SAI200X960. Verify the ISO 15552 mounting interface, the 200mm bore, the 960mm stroke, the G3/4 port, and your mounting accessory. This non-magnet SKU cannot take a sensor; if sensing is needed, order an SAI with the -S suffix for current AirTAC switches. For sizing alternatives, a 160mm bore yields 10053 N push at 0.5 MPa, while a 200mm bore at 0.7 MPa yields 21991 N. Because the 960mm stroke is long, prevent rod bending by guiding the load externally to avoid side-load damage. The plain cylinder does not hold load on air loss; for secure holding, specify the SAIL or BSAI lock variant, or an external pilot check valve.
Replacement checklist
Yes, the SI200X960 is discontinued. The direct replacement is the SAI200X960. It shares the identical ISO 15552 mounting interface, 200mm bore, 960mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
It features a G3/4 port and a 40mm rod. Forces are: 15708 N push and 15080 N pull at 0.5 MPa; 21991 N push at 0.7 MPa; 28274 N push at 0.9 MPa; with a theoretical max of 3204 kgf at 1.0 MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI200X960 replacement — usually within 7-8 hours.
